/echo [-cdeghiNtsaqlbfnmr] [#channel|[=]nick]
Prints text in the specified window using the specified color (0 to 15).
/echo 3 #mIRC Testing
would print "Testing" in the color green in channel window #mIRC, assuming it's already open.
If a channel/nickname isn't specified, the -s switch echoes to the status window, the -d switch echoes to the single message window, and the -a switch echoes to the currently active window.
The -e switch encloses the line in line separators.
The -iN switch indents the wrapped line by N characters.
The -h switch forces lines to hard-wrap so resizing the window doesn't change the line.
The -t switch prefixes the line with a timestamp if global time stamping is on or timestamping is on for that window.
The -q switch makes it not display the text if called from an alias using the . prefix.
The -l switch makes it apply the highlight settings to the line that's displayed.
The -bf switches make it apply the beep/flash settings in the window it is echoing to.
The -n switch prevents the echo from highlighting the window switchbar icon.
The -m switch indicates that the line should be treated as a user message, not an event.
The -g switch prevents the line from being logged to the log file.
The -r switch applies the strip settings in the messages dialog.
The -c switch uses the specified color name from the colors dialog.
